hi
first post here.just picked up a jackpot stampede deluxe machine locally.it needed a battery so i replaced it. first time you turn the machine on it comes up with a ronn 2 error.turn it off then turn it back on it goes through startup one bong , the reels spin and it says dot init then after 5 or 6 seconds it gives a small buzz and says dot fail.
the dotmation screen does initialize and says williams but never goes beyond that...i have an electronics background so the machine seems to have all the right voltages coming from the lower power supply and i def have 12volts on the upper power supply...
i have no access to game software so not sure if eeproms are an issue. any thought?
-
Well, that's promising that the Dotmation screen lights up -- typically "dot fail" is from a dead power supply for the Dotmation display.
Are the correct software EPROMs installed on the board inside the Dotmation box?
-
im not sure because the game eeproms on the cpu are not labeled...
is there any other way to tell?
any place i can get a full set of roms?
the game came with a clear ram chip but I'm not sure of the denomination..
i was told this was specific to each rom?
i appreciate any help

The only "eeprom" in the machine is on the backplane board. All the software chips on the cpu board and inside the dot matrix assembly are "eproms".
With the machine powered on and the main door open look at the card cage just below the shelf that holds the reels. The upper board is the I/O board, on its front edge there is a group of 5 red LED's on the right side of the board and a single red LED on the left side. The single LED should be OFF, the group of 5 LED's should all 5 be ON. If they don't match this description then that's a fail and is usually caused by the lower power supply (the large gray box with the red power switch on the front, mounted on the left wall in lower part of machine, not far from the coin hopper).
If you suspect game software in the eproms on the cpu board they can be replaced or checked. When the machine is powered-up it will do a selftest, if the eproms are ok then the machine will give a single loud "bong" sound. If this happens, and the I/O board LED's are correct then that's a good sign. To check the eproms you'd have to install them into another working machine and see if they work, or you can check them with an eprom programmer to verify their checksums.
These machines are normally reliable other than the power supplies. The dot matrix enclosure (metal box) in the upper part of the machine contains 2 circuit boards. The board on the right side is the 12 volt power supply that operates the dot matrix controller board beside, and the dot matrix display. When you turn the machine on the dot matrix display should light up and show "Williams" and then it displays that it is checking the 2 eproms up there. If that happens then stuff up there is probably ok.
If you need a set of eproms you can pm me about that, but I'd check everything else first. Unless someone messed around with the eproms they are likely ok.

Yes all the leds on the right are lit with the left led is off.
The top display does come on and display willians then counts the roms..
I don’t know where to go from here..
Not sure if the EPROMs are all the same or not..
Any other suggestions?

The CLEAR chip was made for the particular coin denomination of the machine, it is usually a 25 cent CLEAR chip but there are others. The "ronn 2" error refers to "rom 2", which is the DATA eprom at location XU2 or XU3 on the cpu board, I forget which one it is. You can remove XU2 and XU3 and look them over, make sure they don't have any bent or broken legs on the chips. XU2 and XU3 are over on the side of the board in sockets, they contain the main game software. The 4 sockets in the center of the board are for the game sound eproms.
-EDIT- I checked the manual, the data eprom is XU3.

I already have ..
Everything looks good
Any other suggestions?

.....Not sure if the EPROMs are all the same or not..
What do you mean by this??
-
Like I said I bought this machine and I think someone may have
Monkeyed with it..
The EPROMs look like they were a copy and not sure if the ones in the cou match the ones in the display unit
-
well, that makes the eproms an unknown, but not necessarily bad. Like I said earlier you can verify an eprom if you have an eprom programmer ("burner"). Or you can buy a set of eproms for the machine. But these machines are older now, it's not unusual to see non-original eproms in them, lots of people "burn" their own eproms and install them. So the fact that the eproms don't have labels doesn't mean they are bad. But the "rom 2" error you are getting does point to that. But the machine getting thru the initial selftest says the eproms are ok.
The JP Stampede Deluxe machine uses 8 eproms total (5 on cpu board and 3 on the dot controller board located behind the dot matrix screen). Contact me by pm if you want to try a new set of eprom, or just try another XU2 and XU2. I'm not sure that is the problem but if the power supplies (upper and lower) are ok, if there is no battery leakage damage to the cpu board, there are no bent pins on the cpu board edge connectors, there is no water damage to the card cage boards and backplane board, there is no mice-chewed wiring harnesses, and various other things then replacing the eproms might be what is needed.
Did the previous owner give any information, like it was working one day and then died? Did he say if he or someone else tried to repair it? Any clues from the previous owner would help to diagnose the problem. I hesitate to just throw parts into a machine blindly.

The women I got the machine from said it was just working which I know is false now
So I ha e nothing to go on.
I am interested in getting a set if you have one for sale

pm sent, check your NLG inbox.

Have you checked the serial connector going from the backplane to the top logic box? That is the communication between the game and the dotmation screen. If that cable is loose or disconnected, it would throw a Dot Fail message.

hi
i am still having issues with this machine.
i have replaced all of the rams in the machine just to be sure it wasn't programming.
i have checked continuity between the serial cable.checked all connections to dotmation board.
replaced upper power supply no difference.the dotmation screen does light up when it first comes on and says williams and counts roms.
all cables have been checked...
would anyone have a dotmation controller board for sale?
thats the only other thing i think it could be???
any other suggestions would be greatly appreciated
-
I have one. Bill

how much?

Have you tried plugging the serial cable into the other port on the dotmation board? There should be 2 ports, either one would work.

Trying to send you a message but your NLG inbox is full

Ok all set you can send

Hello I am having a similar issue did you ever resolve this?
